• Embedded SCSI bus interface (SCSI-2).

• 256-kbyte buffer memory on the SCSI controller.

• Audio CD like drawer loading of a disc without using a caddy.

• Power loading and power eject of a disc. The disc can also be

ejected manually.

• Housed in an airtight frame casing.

• Equipped with a parity on/off switch.

required to support CD-ROM XA and CD-I compatible audio

modes. In addition, the unit does not support the CD-I graphic

decoding function; it has to be provided by the system.

Software Requirement

MSCDEX (supplied with the host adapter) must be installed in your

computer. See the manual that comes with the host adapter for

details.

The application software you need for using the data on a CD-ROM

disc depends on the type and format of the target data. See the

manual supplied with your CD-ROM disc for instructions.

Precautions

■Installation

• Avoid placing the drive in a location subject to:

– high humidity

– high temperature

– excessive dust

– mechanical vibration

– direct sunlight

• The drive can be used in either a horizontal or vertical position.

• Do not force the power cable. It is keyed to protect the drive.

■Operation

• Do not move the drive when it is in use. Doing so may cause data

error and damage the optical pick-up.

• Avoid exposing the drive to sudden changes in temperature as

condensation may form on the lens inside the drive. Should the

surrounding temperature suddenly rise while the drive is turned

on, stop using the drive and leave the power on at least one hour

before operating it or turning it off. Operating the drive

immediately after a sudden increase in temperature may result in a

malfunction.

■Transportation

• Close the disc drawer before moving the drive.

• Keep the original packing materials. When you need to ship the

drive to another location, repacking it in its original container will

help you transport it safely.
